It works correctly here with 12.14. Have you checked to make sure fit-to-width is disabled? (Fit-to-width is toggled on and off via CTRL+F11). Also, have you checked to make sure a 'style' setting hasn't been disrupted? (In Menu > View > Style, make sure "author mode" is checked, make sure each of the 16 or so detailed options at the bottom of that pop-up are unchecked, and under Manage Modes > Display make sure only "show active frame border" is unchecked.)
